Michal Ždanský First introduced in June of this year, the new Mac Pro has already found its way into the hands of a few lucky owners and reviewers. The revolutionary miniature workstation has been lauded many times in reviews, and Apple's new computer is perhaps best described by the phrase that "the whole is greater than the sum of its parts." Other World Computing even took apart the Mac Pro and revealed a few interesting facts.
Probably the most important of them is the fact that the computer's processor (Intel Xeon E5) can be changed by the user. Unlike other Apple computers, it is not welded to the motherboard, but is inserted into the standard LGA 2011 socket. This applies to all four types of processors that the company offers in Mac Pro configurations. This means that users can buy the lowest configuration, wait for better processors to come down in price, and then upgrade. Since the top processor comes in at an extra $3 (500-core Intel Xeon E12 5GHz with 2,7MB L30 cache), the upgradeability is a boon. The only condition is explicit support for the given processor, since OS X, unlike Windows, only has a modest list of compatible hardware.
But it's not just the processor. Operating memories and SSD disks are also user-replaceable. Although it is not possible to add additional internal drives or even change graphics cards, as was possible with older Mac Pros (graphics cards for the new Mac Pro are custom), however, compared to iMacs, the options for upgrades without having to pay Apple's premium price are quite abundant.
However, Apple is more likely to count on external devices when it comes to storage expansion. High-speed Thunderbolt 2 ports with a throughput of up to 20 GB/s in both directions are used for this. The Mac Pro also allows you to connect up to six Thunderbolt displays and can handle 4K displays as well.
The interesting thing about the new Mac Pro is that the price of components is higher than the price for which Apple sells complete sets. http://appleinsider.com/articles/13/12/24/apples-new-mac-pro-a-better-value-than-the-sum-of-its-parts
Which is unusual for Apple.
